OK,
It appears you are using a ballistics program. I wondered, because I cannot recall ever having seen RL-17 paired with the 348 WCF in any published data. After reviewing your results, I wonder why that is the case!
One more thing, B., Don't know if its just the photo, but your pic. of the loaded round oal seems to be sporting a shiny ring just above the case head. I have an old lot of Remington brass I saved for posterity that sports the same ring, in the same place. My concern is that this is a sign for incipient case head separation.
Those Woodleighs sure look nice, and unlike Hawk, they have a cannelure.
Thanxs for keeping us up to date.
